Using data from the Consumer Expenditure Survey and the March Current
Population Survey, we provide poverty estimates for 1967 to 2012 based on a
historical Supplemental Poverty Measure (SPM). During this period, poverty, as
officially measured, has stagnated. However, the official poverty measure (OPM)
does not account for the effect of near-cash transfers on the financial
resources available to families, an important omission since such transfers have
become an increasingly important part of government anti-poverty policy.
Applying the historical SPM, which does count such transfers, we find that
trends in poverty have been more favorable than the OPM suggests and that
government policies have played an important and growing role in reducing
poverty—a role that is not evident when the OPM is used to assess
poverty. We also find that government programs have played a particularly
important role in alleviating child poverty and deep poverty, especially during
economic downturns.
